Targ and Spectar use slightly different sound boards. I have both game PCBs in my collection.

The Spectar firing sound (shot.wav) is different from Targ and has been wrong all these years. I will upload the correct one soon.
Spectar needs to have it's samples defined separately so it calls spectar.zip in samples (Right now it is just using targ.zip samples) but you can use the same sample names as targ and I will make a new samples zipfile. Can someone do that for me?

New sample shot.wav attached with existing targ samples that are the same.

In audio\targ.cpp

Make this change to fix Spectar's long explosion. (all it is the reverse) This doesn't fix targ however because when you crash it plays the short explosion instead of the long one. I have not figured out why.
